Polarization test
Before testing, make sure that the electrical and mechanical
protection of the linear motor system is well configured!
Make sure that there is an effective protective earth. Make sure
that there is no voltage at the wire terminals before connecting.
There is one regular way of testing the polarization. Some servo amplifiers
can operate in an in moment service mode. By means of regulating an ex-
ternal resolver manually, it can be determined whether the motor’s direc-
tion of running conforms the resolver’s sense of rotation. If so, the motor
is well connected. If not, two phases of the power cable – phase 1 and 3
– must be changed.
Internally all ironless linear motors are equally wired and connected, so one
test satisfies to find out the polarization of a motor ruler combination. If
more axes are constructed in exactly the same way the polarization will be
equal.
